YG1 55901TN 1/4″ Size, 1-1/2″ LOC, 4 Flute, TiN Solid Carbide Finishing End Mill New Release

Applications

The YG1 55901TN solid carbide finishing end mill combines a 1/4″ diameter with a 1-1/2″ length of cut, yielding a rigid 6.0x length-to-diameter ratio that supports precision machining in confined depths. This balance of reach and stiffness makes it ideal for detailed finishing passes on steel and cast iron components where control and surface quality are essential. Its 4-flute design, 30° helix angle, and TiN coating optimize chip evacuation and cutting edge strength. This tool enhances performance in free-machining steel and general milling, reducing wear and maintaining sharpness during moderate-speed operations. Travers Tool offers this model as a dependable solution for machining steel (ISO P) and compatible materials. However, it is unsuitable for heat-resistant superalloys (HRSA ISO S) due to coating unsuitability. The sharp corner design requires careful handling to avoid chipping during interrupted cuts and does not provide corner radius protection.

Features

• Suitable for cutting hardened & high alloy steels, steel casting, chill casting, malleable cast iron, CrNi-steels, brass, copper, aluminum with a high percentage of silicon and abrasive plastics.
